After coming in second on Food Network’s “Cake Wars,” they were competing on “Winner Cake All,” hosted by superstar chef Giada De Laurentiis. They are in the ninth episode of this first season.

The challenge: Bake a decorated mega-cake in five hours for Guy Fieri to celebrate the 250th episode of “Guy’s Grocery Games.” The winning cake would be driven to the set in Santa Maria the following day, and best of all, the winning team would take home $10,000.

“We have to make it fun, bright and colorful,” said Sally, who quickly began the mocha cake with mocha whipped cream – Guy’s favorite flavor, they learned, is coffee – while Sherry started creating the structure.

“Any big cake needs an armature,” she said. “We used PVC pipe to hold the cake and decorated it to look like a shopping cart. It was my first time making a cake that big.”

“It was for Guy,” added Sally. “We had to make it over the top.”

The sisters appeared wearing cats’ ears – between them they have five cats.

After graduating from the Cordon Bleu in Pasadena, Sally did her internship at Simply Irresistible in La Habra.

“I worked for a lot of bakeries, but I wanted to start my own.” she said. “I learned a lot of stuff on YouTube about decoration. Culinary school was more about pastries, French style cuisine, croissants and stuff like that.”

The sisters had been baking for years.

“Growing up we didn’t have a lot of money, so baking cakes was our way of getting creative. We’d give them as gifts,” recalled Sherry. “We always cooked with my mom. We loved eating sweets, so we’d try a recipe over and over, experimenting with frosting and decorating. My Grandma was a really good baker. She made these Vietnamese sesame cookies. She would take her cart and go sell them around the neighborhood.”

Their parents were refugees who fled Vietnam during the war.

“Seeing my mom work so hard just to provide for us – she gave us the life we needed,” said Sherry. “We’re doing what we love.”

Sally and Sherry are presently searching for a location to open The Gateaux Shoppe in Anaheim Hills.

“We wanted Fullerton, because our hearts are in Fullerton, but there’s bakeries on every corner,” said Sally.

In the meantime, check out The Gateaux Shoppe on Instagram and Facebook for photos of their amazing pastries and cakes for weddings and every occasion.

“We even make cakes for dogs using carrots, peanut butter, whole wheat, stuff that dogs can eat,” Sally said. “We have a video of my friend’s dog eating it, and he was just like chowing down. So cute.”

Sally was flown to Seattle once to do the cake and dessert table for a Bat Mitzvah, and on the day we met she was rushing home to start 300 Oscar cookies for a real estate office.

So did they win the “Winner Cake All” challenge? You bet.

“Now we can buy lots of cats,” said Sally.
